At the age of 14, Ellie discovered her immunity to the Cordyceps brain infection, and Marlene, leader of the Fireflies, believed she held the key to a vaccine. Joel Miller, a smuggler, was tasked with escorting Ellie, leading to a year-long journey across America. Joel learned that sacrificing Ellie was necessary for a cure, but he chose to save her, leading to Ellie resenting him for the next four years. In 2038, Abby Anderson, a former Firefly, killed Joel, prompting Ellie’s quest for revenge. After pursuing Abby to Seattle and retiring on a farm with her family, Ellie couldn’t forgive Abby and pursued her to Santa Barbara, ultimately choosing to spare her.
